MaxxWave MW-UTP-G-US compatibility in CRS switches?

Thu Jan 26, 2023 9:21 pm

We recently purchased a couple MaxxWave MW-UTP-G-US 1000Base Copper SFP to put into a CRS326-24S+2Q+RM running RouterOS 7.7. However, when I installed them, the CRS doesn't appear to even know it was plugged in. There are no entries in the event log on the CRS. I even enabled debug logging and still nothing when I plugged and unplugged the MW-UTP-G-US. I tried multiple slots on the CRS326 and same results. A MaxxWave fiber SFP works fine in the CRS, so it doesn't appear to be an issue with the slots on the CRS. According to my reseller, this SFP should be compatible with MikroTik devices. As an interesting note, I tried the MW-UTP-G-US in an HP switch and it worked immediately, so it's not a faulty SFP.

Does anyone know how to make this module work in the CRS326-24S+2Q+RM device?

And there is no info about the SFP either?

Copper SFPs can be tricky, especially when mixing vendors. Always try to force speed & duplex.
